The Salton Sea is one of numerous new mining proposals in a global gold rush to find new sources of metals and minerals needed for electric cars and renewable energy.
Thanks to the New York Times for this coverage of the choices surrounding how and where to mine a key ingredient of more efficient batteries–a consequential environmental question:
A race is on to produce lithium in the United States, but competing projects are taking very different approaches to extracting the vital raw material. Some might not be very green.
“This is the most sustainable lithium in the world, made in America,” Rod Colwell, the chief executive of Controlled Thermal Resources, said. “Who would have thought it? We’ve got this massive opportunity.”
Atop a long-dormant volcano in northern Nevada, workers are preparing to start blasting and digging out a giant pit that will serve as the first new large-scale lithium mine in the United States in more than a decade — a new domestic supply of an essential ingredient in electric car batteries and renewable energy.
The mine, constructed on leased federal lands, could help address the near total reliance by the United States on foreign sources of lithium.
But the project, known as Lithium Americas, has drawn protests from members of a Native American tribe, ranchers and environmental groups because it is expected to use billions of gallons of precious ground water, potentially contaminating some of it for 300 years, while leaving behind a giant mound of waste.

Stewardship has rights and responsibilities, and we expect better both from and for Brazil in their stewardship of the Amazon region. For our part, among other things, we can all avoid purchasing products that result from this deforestation:
International team of researchers also found that deforestation rose nearly four-fold in 2019

The Brazilian Amazon released nearly 20% more carbon dioxide into the atmosphere over the past decade than it absorbed, according to a startling report that shows humanity can no longer depend on the world’s largest tropical forest to help absorb manmade carbon pollution.
From 2010 through 2019, Brazil’s Amazon basin gave off 16.6bn tonnes of CO2, while drawing down only 13.9bn tonnes, researchers reported Thursday in the journal Nature Climate Change. Continue reading

Thanks to Jonathan Mingle and Yale e360 for this analysis:
Ending the use of fossil fuels to heat homes and buildings is a key challenge for cities hoping to achieve net-zero emissions. Nowhere is that more evident than in Philadelphia, where technical and financial hurdles and a reluctant gas company stand in the way of decarbonization.
In 1836, Philadelphians mostly used whale oil and candles to light their homes and businesses. That year, the newly formed Philadelphia Gas Works caused a stir when it lit 46 downtown street lamps with gas made from coal in its plant on the Schuylkill River. Continue reading

The Guardian features this gallery of photos with commentary, by Marcus Westberg, to raise awareness; click any image to see the entire collection:
Each year, about 1% of Sweden’s forest is cut down, according to the trade association Swedish Forest Industries, mainly in the northern half of the country. Since 2000, Sweden has lost more than 48,000 sq km (19,000 sq miles) of tree cover, not accounting for replanting, or 17% since 2000, according to Global Forest Watch. It is an area greater than Denmark
Forests cover 70% of the country, but many argue the Swedish model of replacing old-growth forests with monoculture plantations is bad for biodiversity.

Fossil fuel divestment is easier said than done. Some in the creative sector have fostered skepticism about climate change. A message from some creative folks that we are inclined to believe:
Clean Creatives is bringing together leading agencies, their employees, and clients to address the ad and PR industry’s work with fossil fuels. Continuing to work for fossil fuel companies poses risks to brands that prioritize sustainability, and their agencies. Continue reading

Thanks to Nicola Jones, as ever, and to Yale e360 for publishing this explanatory article on a relatively new topic:
Seagrasses, mangrove forests, and coastal wetlands store vast amounts of carbon, and their preservation and restoration hold great potential to bank CO2 and keep it out of the atmosphere. But can the blue carbon market avoid the pitfalls that have plagued land-based programs?

Off the shores of Virginia, vast meadows of seagrass sway in the shallow waters. Over the past two decades, conservation scientists have spread more than 70 million seeds in the bays there, restoring 3,600 hectares (9,000 acres) of an ecosystem devastated by disease in the 1930s. The work has brought back eelgrass (Zostera marina) — a keystone species that supports crustaceans, fish, and scallops, and is now absorbing the equivalent of nearly half a metric ton of CO2 per hectare per year.

Reducing synthetic nitrogen in farming, by letting legumes do more nitrogen-fixing in the soil, has plenty of other benefits:
Plant more bean-like crops in Europe and consider ‘healthy diet transition’ to beat climate crisis, say scientists
Adding the likes of peas, lentils, beans, and chickpeas to your diet, and farming more of them, could result in more nutritious and effective food production with large environmental benefits, scientists have found. Continue reading

We have committed to planting trees. And we know that getting to a trillion trees planted is not going to be easy. But the effort has obvious and less obvious upsides. Every great idea also has its downside(s) and challenges to surmount, even planting trees:
High-profile programs aimed at planting billions of trees are being launched worldwide. But a growing number of scientists are warning that these massive projects can wreck natural ecosystems, dry up water supplies, damage agriculture, and push people off their land.

This is a short read with a big implication; as always we are grateful to Bill McKibben for his weekly newsletter:
When a respected naturalist mentions eBird, or the Cornell Lab of Ornithology, our family’s attention is rapt. I now realize that Scott Weidensaul first appeared in our pages in 2012, and then twice since then before today. This time is different because he is interviewed by Dave Davies, one of the great conversationalists of our time, and they are discussing Mr. Weidensaul’s new book (click the book image above to order it from a non-Amazon source). The discussion does not shy away from the challenges related to bird populations, but has plenty to smile at too:
Scott Weidensaul has spent decades studying bird migration. “There is a tremendous solace in watching these natural rhythms play out again and again,” he says. His new book is A World On the Wing. Continue reading

Kelp is being farmed now, but where it is a naturally occurring forest it needs help. Thanks to National Public Radio (USA) for this:
They’re purple, spiky and voracious, and just off the West Coast, there are more of them than you can count.
Purple sea urchins have exploded in recent years off California, covering the ocean floor in what divers describe as a “purple carpet.” Continue reading
GETTY IMAGES. Scotland’s renewables output has tripled in 10 years
Thanks to Scotland, for the ambition and demonstration; and to the BBC for reporting this:
GETTY IMAGES. WWF Scotland is calling for an increased roll-out of electric vehicles
Scotland has narrowly missed a target to generate the equivalent of 100% of its electricity demand from renewables in 2020.
New figures reveal it reached 97.4% from renewable sources.
This target was set in 2011, when renewable technologies generated just 37% of national demand. Continue reading
A coal-fired power plant in China’s Jiangsu province. XU CONGJUN – IMAGINECHINA
What is the real intent on addressing climate change, we must wonder:
China is building large numbers of coal-fired power plants to drive its post-pandemic economy. The government has promised a CO2 emissions peak by 2030, but the new coal binge jeopardizes both China’s decarbonization plans and global efforts to tackle climate change.
China’s National People’s Congress meetings, which ended earlier this month, were shrouded in both a real and figurative haze about how strong its climate ambitions really are and how quickly the country can wean itself from its main source of energy — coal. Continue reading
Art from Beloved Beasts by Michelle Nijhuis. Illustration: Courtesy of Norton
My interest in the history of conservation started with the discovery of an archive full of hotel guide books from earlier centuries, which led to another archive full of data about one of the earliest publicly-funded conservation projects, which in turn led to my doctoral dissertation. My particular interest is in the history of both conservation and tourism and their co-evolution over the past century. And this interest seems to run in the family, which might explain where our family’s various entrepreneurial activities have emerged from. All along the way, science writers have been a favorite source of nourishment. I can better understand Michelle Nijhuis‘s two-year hiatus from our pages thanks to Rachel Fritts, Editorial Intern at Audubon magazine, in this author interview:
In her new book ‘Beloved Beasts,’ author Michelle Nijhuis chronicles a movement dedicated to the ‘preservation of possibility.’

Veteran science journalist Michelle Nijhuis has been writing about conservation for more than two decades. Her work on topics ranging from climate change to humans’ relationships with other species regularly appears in publications such as the New Yorker and The Atlantic. In her hotly anticipated new book, released March 9, Nijhuis sets out to tell the definitive history of the effort she dedicated her career to chronicling.
Beloved Beasts: Fighting for Life in an Age of Extinction turns an exacting eye on the history of conservationism, emphasizing the movement’s interconnectedness and complexity. Nijhuis takes the reader on a journey through time, from the plains bisons’ brush with extinction in the 1800s, to the community conservancies preserving wildlife in modern-day Namibia.

The message from Elizabeth Kolbert’s book should sound relevant to you when you read the following:
In China, scientists have turned vast swathes of arid land into a lush oasis. Now a team of maverick engineers want to do the same to the Sinai
Flying into Egypt in early February to make the most important presentation of his life, Ties van der Hoeven prepared by listening to the podcast 13 Minutes To The Moon – the story of how Nasa accomplished the lunar landings. The mission he was discussing with the Egyptian government was more earthbound in nature, but every bit as ambitious. It could even represent a giant leap for mankind. Continue reading
